Patented Nov. 26, 1929 Unirse star PATgT FFIC` ADJUSTABLE HOLDINAGDEVICE Application led May 27, 1927, Serial No. 194,569. Renewed August12, 1929.

rlhis invention relates to improvements in adjustable holding devices,and refers more particularly to holding devices for holding ythe outerends of pivotally .connected mem- 5 bers at varying distances from fixedmembers, or for holding the outer ends of two ymembers pivotallyconnected to one another lvat Varying distances apart. It is an objectof the invention to provide 1Q an adjustable holding device which can bequickly and easily set so as to maintain a pivotally mounted member vatvarying distances from a Xed member on which it is mounted, either whenthe outer margins of 15 the said members are substantially in the sameplane and adjacent to one another, or when the pivotal member is swungaway vfrom the fixed member and has its outer marl gin inclinedatanangle to the margin of the 2c fined member.

Another object of the invention is to pro-V vide an adjustable holdingdevice which can be cheaply and easily made and applied.

Having thus outlined the major purposes 25 of the invention I will nowproceed to describe an embodiment thereof with the aid of theaccompanying drawings, in which:

Figure 1 illustrates a perspective view of the invention with the uppermargin ofthe pivotal member inclined at an angle to the fixed member,and

Figure 2 is an end view of Figure 1.

Figure 3 shows a plan view of the invention, and

2.5 Figure 4 is a side view thereof.

Figures 5 and 6 are sections on the lines 5-5 and 6 6 of Figure 3.Figures '7 and 8 are details of the arm and slide.

Referring to the drawings, 1 designates a window pivotally mounted at 2in a window frame 3. On the latter an angle plate 4, having asubstantially horizontal upper surface 5, is provided. The said uppersurface Y has an opening 6 therethrough to receive the 45 downturned end7 of an arm 8, the opposite end of which latter has an aperture 9therethrough.

On the upper margin 10 of the window 1 a guide plate 11 is secured. Thisguide plate plate has a longitudinal raised bearing surface 12 throughwhich an elongated slot 13 is cut. The outer margin of the bearingsurface portion 12a adjacent to the window frame 3 is longitudinallysubstantially parallel with the underside of the guide plate, whereasthev 5 outer margin of the bearing surface portion 12b remote from thewindow frame 3 is upwardly inclined from the end A of the guide plate toits end B that is upwardly inclined towards the end of the bearingsurface directly opposite the plate4. It will also be noted `that thebearing surface portions 12'pl and 12b are substantially parallel withone another transversely throughout their length, and are gradually at alesser angle to the` underside of the guide plate from't-he end B ofthelatter until they are substantially parallel with the underside of thesaid guide plate at its end A. 1 l

A slide 14 is provided under the bearing surface which is wider than theslot 13, and has an upwardly projecting pin 15 thereon which passesthrough the said slot'. Moreover it will be noted that the pin ispreferably providedwith aV flat side 15a thereon which bears against oneside of the slot 13 so that. the slide is positively-held againstrotation. The upper portion ofthe pin is threaded, passes through theaperture9 in the arm 8, and has a nut 16 in threaded engagement with :13it, so that by tightening the nut the arm is clamped between it and thebearing surface 12.

'It is of course obvious that the angle of ineline of the outer bearingsurface portion 129.535 longitudinally must be made to suit the lengthof the window 1 from its pivotal point 2 to its upper margin 10, sinceone object ofthe invention is to provide a guide plate having Y abearing surface so formed as to compensateeo for the varying angularitybetween the upper surface 5 ofthe plate 4 and the margin 10 of thewindow 1 as the latter moves pivotally, since the outer end ofthe arm 8is always at the same location along the bear-3195 ing surface when thepivotally mounted window is swung outwards a given distance, and isinclined at a given angle.

While in the foregoing the preferred embodiment of the invention hasbeen describedi-'loo and shown, it is understood that the constructionis susceptible to such modifications as fall Within the scope of theappended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. A device of the character described comprising a guide having alongitudinal raised bearing surface, ksaid bearing surface having anelongated rslot therethrough, the bearing surface on one side of saidslot having its outer margin substantiaiiy `parallel with the undersideof the guide and the .bea-ring surface on the other side of the slothaving its outer margin' upwardly inclined from one end, and an armhaving one end adapted to vbe Lpivotally mounted and its opposite endextendingzover said slot, in combination with means extending throughsaid slot for holding said opposite endof said arm against said hearingsurface `at any location therealong. l
